DYNAMO-ELECTI'R-IG MACHINE.

SPECIFICATION formingpart ofv Letters PatentlNo. 249,241, dated November 8, 1881.

Application tiled March 22, 1881.

To all whom it may concern Beit known that I, CHARLES A. HUssEY, of the 'city of New York, in the county and State ofv New York, have invented` certain new and useful Improvements in Dynamo-Electric Machines, ot' which the following is a specilication.

The object of my invention is to produce a simple and desirable armature for a dynamo or magneto electric machine.

My armature is composed. of a hollow body or core and hollow radial extensions communicating with the interior of the body and furnished with connected coils of wire. Acirculation of air will be maintainedthrough. the bodyT -or core and extensions of the armature when it rotates, and will serve to keep it cool.

In the accompanying drawings, Figure lis a plan of an armature embodying my improvements,iand a commutator therefor. Fig. 2 is a diagrammatic View comprising a transverse section of the armature, a perspective view of acommutator therefor, and vthe wires leading from the armature; and Fig. 3 is a planofthe armature with the coils of wire on its extensions dift'erently connected, and a number of commutators therefor.

Similar letters of reference designate corresponding parts in all the figures.

A designates a cylindrical body or core, which isvhollow from end to end, and may be made of wrought-iron `or any other suitable material.

B designates a number of radial extensions, whichconsist of tubes of similar material, screwed into or otherwise secured to the body or core, A, made open from end to end, and

communicating with the interior of the said body or core. On-these radial extensions are coils ot' wire E E', Sto., which are wound in the form of inverted frusta of cones, or, in other words, in the form of frusta of cones arranged` with their smaller ends next the body or core A. These coils are wound in the form described, so that they will t close together circumferentially around the body or core, and hence so that the greatest possible amount of wire may be employed in the least possible space. At the outer ends they also t closely (No model.)

togetherlengthwise of the body or core. These radial extensions. B are arranged in circular rows and inv line lengthwise of the body or core. The coils ot wire on the radial extensions may bewoond on any suitable contrivance, and slipped over the radial extensions after beingwound. When this armature rotates the outer end ot' these radial extensions are intended totravel in close proximity to the field-magnets oi' a dynamo or magneto electric machine, so that currents of electricity will be generated in the coils of wire on thesaid radial extensions. The coils ot' wire on said radial extensions may be connected in Various ways, as hereinafter more particularly explained. As here shown', there are eight of these radial extensions in each row around the bodyor core of the armature, and eight arranged in line lengthwise ofthe same.

To each end of the body or core A ot' the armature there is tted a disk or end plate, C. A shaft, D, extends through these disks, and its ends protrude beyond the disks and form journals, on which the armature rotates. As shown, these disks have flanges a, which enter the body or core A, and are secured in place by screws b, entering the ends of the body or core, so as to be interlocked positively therewith, to turn therewith. rlhese disks may 1. have openings for the admission of air, and:vl

the air entering these openings will, vas the sus armature rotates, be carried into the body or i core, and will pass thence to and out of the radial extensions, thus keeping the armature cool.

On one of thejournals of the armature shown in Fig. l is a commutator, F, which, as here shown, is intended to have eight plates. The outside end ofthe wire of the coil E, on a radial extension near one end of the body or core, is connected to the inner end of the coil E on the nearest radial extension, which is arranged inline with kit lengthwise of the body or core. The outer end of the coil E is connected to the inner end of the coil E2, and so on to the last coil, E7, of the row. The outer end of the coil E7 is connected by what I term a loop, c, to the inner end ofthe adjacent coil, E8, of the next longitudinal row. The coils in this row are suci cessively connected, as before, to and including the last coil, E15, of the row. The outer end ot' the coil E5 is connected by a loop, c', to the inner end ofthe adjacent coil, E16, ofthe next longitudinal row. The coils in this row are similarly connected, and the outer end of the last coil, E23, is connected by a loop, c2, to the inner end of the adjacent coil, E2, ot' the next longitudinal row. The coils ot' the last-named row are similarly connected, and the outer end of the last coil, Ef, is connected by a loop, c3, to the inner end of the adjacent coil of the next longitudinal row. The coils in that row are connected as before, and the last coil, E39, ofthe row. The outerend of this coil Emis connected by a loop, c, to the inner end of the adjacent coil of the next longitudinal row. The remaining coils are similarly connected to and incl uding the coil E63, which is adjacent to the coil E. The outer end ofthe coil EG3 is connected by a loop, el, to the inner end ofthe coil E.

Leading-wires d d d2 d3 d4 di d di extend from the loops c c c2 c" c1 c5 cG c7 to the plates e e c2 cil c c5 c e7 ofthe commutator F. Brushes G, of ordinary or other suitable form, are used in connection with the commutator.

ln the armature shown in Fig. 3 the outer end oi' one coil, E, is connected by a loop, c, to the inner end ofthe coil El5 next to it circum t'erentially of the body or core of the armature, and the outer end ot' the coil E15 is connected by a loop, c', to the inner end of the adjacent coil, Em. The coils are connected throughout the armature' in circumferential rows by loops c c', &c., as indicated lin said ligure, and leading-wires d d', &c., extend from said loops to plates c ot' commutators F, one commutator being provided for each circumferential row ot' coils. ln the rotation ot' this armature eight separate electric currents will be generated. Brushes are to be provided for each commutator. The brushes of these commutators may be connected for either quantity or intensity, as may be desired.

I have not attempted to explain all the ways in which the coils on the radial extensions of the armature may be connected, as these ways are almost illimitable and will suggest themselves to those skilled in the art to which these improvelnents appertain after the few examples of different connections I have given. I desire, however, to remark, further, that the coils on the radial extensions may themselves be connected either for quantity or intensity.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. An armature for a dynamo or magneto electric machine, composed of a hollow cylindric core, with openings at the ends for the admission ot' air, and radial extensions communicating at the inner ends with the interior of the body or core, open at the outer ends, and furnished externally with connected coils of wire, substantially as specified.

2. An armature composed ot' a hollow body or core, disks or end plates provided with openings t'or the entrance of air to the body or core, and tubular radial extensions furnished with connected coils of wire, substantially as specitied.

3. The combination, with an armature comvposed ot' a hollow7 body or core and hollow radial extensions wound with wire, of one or more colnmntators connected with said coils ot'wire, substantially as specified.
